AWNING.

SPECIFICATION formingpart of Letters Patent N 0. 711,850, dated October21, 1902. Application filed February 26, 1902. Serial No. 95,693. (Nomodel.)

To all whom it may concern.-

Be it known that I, CLARENCE SLOAN HAM- ILTON, a citizen of the UnitedStates, and a resident of Salem, in the county of Marion and State ofOregon, have invented a new and Improved Awning, of which the followingis a full, clear, and exact description.

The object of the invention is to provide a new and improved awningwhich is simple and durable in construction and arranged to permit ofconveniently and quickly extending the canvas or moving it into aninactive position by the operator simply turning a crank.

The invention consists of novel features and parts and combinations ofthe same, as will be more fully described hereinafter and then pointedout in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 isa perspective'view of the improvement as applied and in anextended position. Fig. 2 is an enlarged front elevation of theimprovement, showing the webbing wound up on the roller. 7 Fig. 3 is atransverse section of the same on the line 3 3 ofFig. 2, and Fig. eis asimilar view of the same in an extended position.

The awning-roller A is journaled in suitable bearings B. attached to theface of the building O on which the awning is to be used, and on thesaid rollerA winds and unwinds the webbing D, of canvas or othersuitable material, provided on its free end with a stretcher-bar E,onwhich are secured the outer ends of the extension members F of side armsF, pivoted on bearings B, secured to the face of the building 0 adistance below the bearings B. Each extension member F is provided atits inner end with a block F mounted to slide on the arm F, and the saidextension member is guided loosely in a block F secured to the outer endof the arm F. An outward and inward sliding movement is given to theextension members F of the side arms F at the time the webbing D isunwound or wound up on' the roller A, and for this purpose the followingdevice is provided.

Two ropes G and H are arranged for each side arm and its extensionmember, the rope G being secured to the block F to then ex-' tend over apulley G, journaled in the block F the rope then passing under a pulleyG journaled on a bracket 13 secured to the face 7 of the building 0, therope then extending upward to wind on the driving-shaft I, journaled insuitable bearings B secured to the building 0 a short distance below thebearings B. The other rope H is secured to the block F and then extendsunder a roller H, journaled on a bracket B the rope then extendingupward to wind on the shaft I in an opposite direction to the rope G.Now when the shaft 1 is rotated in one direction then one of the ropes Gand H is wound up,

.while the other is unwound, and when the several parts are in theposition shown in Fig. 3 and the shaft I is turned in the direction ofthe arrow a then the ropes G are wound up on the shaft I, while theropes II unwind, and the said ropes G exert a pull on the blocks F andcause the extension members F to slide outwardly on the arms F. When theshaft 1 is turned in the inverse direction of the arrow a, then theropes H wind up on the shaft I, while the ropes G unwind, andconsequently the ropes H exert a pull on the blocks F so as to draw thesame inward, and consequently move the extension members F into thefolded position shown in Figs. 2 and 3.

In order to rotate the shaft 1 in either of the directions mentioned, Iprovide the said shaft with a sprocket-wheel J, connected by asprocket-chain'J with a sprocket-wheel J journaled on the face of thebuilding 0, near the sidewalk thereof, as plainly indicated in Fig. 1,so that the operator turning the crankarm K on the said sprocket-wheel Jcauses rotation of the shaft in one direction, accordin g to thedirection in which the" crank-arm K is turned. At the same time that theextension members F are caused to move into an extended or a foldedposition the roller A is turned to unwind or wind'up the webbing D, andfor this purpose the roller A is driven from the shaft I, the latterbeing provided with a sprocketwheel L, connected by a sprocket-chain Lwith a sprocket-wheel L on the said roller A. flhismovement of theextension members F is in. unison with the rotation of the roller A. i

As shown in Fig. 1, the awning-roller is located below the transom ofthe building 0,

so that light can at all times pass through the; transom into thebuilding whether the awn ing is rolled up or extended.

The device is very simple and durable in construction, is composed ofcomparatively few parts, and requires but little exertion on the partofthe operator for turning the crank-; arm K to extend the awning or toroll the webbing up and fold the side arms against the face of the housewhen the awning is not to be used.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent- 1. An awningcomprising a roller, a webbing adapted to wind and unwind on the andunder the control of the operator, a gear ing between the shaft and thesaid roller, and

roller, pivoted side arms having extension members connected with thefree end of the said Webbing, means for simultaneously rotating theroller to wind up or unwind thewebbing and to fold up or extend the saidextension members on the said side arms while swinging the latter up ordown, the said means comprising a shaft mounted to turn ropes connectedwith the extension members, and arranged so that one set of ropes windsup on the shaft while the other unwinds, as;

set forth.

, 3. An awning having a shaft under'the control of the operator, sets ofropesof which one set winds up on the said shaft and the other unwindstherefrom at the time the shaft is rotated in one direction, pivotedside arms having extension members mounted to slide on the sidearms,'the said extension members being connected with the sets of ropes,and guide-pulleys for the said sets of ropes, as set forth.

4. An awning having a shaft under the control of the operator, sets ofropes of which one set windsup on the said shaft and the other unwindstherefrom at the time the shaft is rotated in one direction, pivotedsidearms having extension 'members mounted to slide on the side arms,the said extension members being connected with the sets of ropes,guidepnlleys for the said sets of ropes, a roller rotating in unisonwith the said shaft,-and a webbing winding and unwinding thereon andconnected with the free ends of the said extension members, as setforth.

5. In an awning, pivoted sidearms having guides at their outer ends,extension members having guides at their inner ends mounted to slide onthe side arms, the said extension members being connected at their outerends with theawning-webbing and extending through the guides at theouter ends of the side arms, a set of ropes secured to the guides at theinner ends of the extension members and passing over pulleys [journaledin the guides at the onter'ends of the side arms, a second set'of ropesalso secured'to the said guides at the inner ends of the extension.members, guide-pulleys for the said sets of ropes, and means forwinding and unwinding the sets of ropes, as set forth.

In testimony whereof I have signed my name to this specification inthepresence of two subscribing witnesses.

CLARENCE SLOAN HAMILTON.
